Descripción
The effects of sunflower hulls (SFH) inclusion on performance, TTAR of nutrients, ileal mucosa morphology, and volatile fatty acid (VFA) concentration in the ceca were studied in birds from 1 to 21 d of age. There were 4 treatments organized as 2 × 2 factorial with 2 chicken lines (broilers vs. pullets) and 2 levels of SFH (0 vs. 3%). Each treatment was replicated 7 times (10 birds). The corn-soybean meal control diet contained 3,010 kcal AMEn/kg, 1.25% digestible Lys, and 8.7% NDF. In the experimental diet, SFH was included at the expense (wt:wt) of the control diet. Diets were offered in mash form. No interactions between main effects were detected for any trait. From 1 to 21 d of age, ADG was greater and FCR was better in broilers than in pullets (P < 0.001) but SFH inclusion did not affect bird performance. The TTAR of all nutrients was higher (P < 0.05) in broilers than in pullets. The inclusion of SFH improved AMEn of the diet (P < 0.05) at both ages and DM and N retention (P < 0.001) at 21 d. Broilers had larger villus and deeper crypt (P < 0.01) than pullets. Broilers tended to have higher (P = 0.077) cecal proportion of acetate than pullets but no effects were observed for the other VFA. SFH inclusion tended to increased villus height (P < 0.05) and cecal proportion of acetate and propionate (P < 0.01). In summary, broilers grew faster, were more efficient, had higher ileum absorptive capacity, TTAR of nutrients than pullets. The inclusion of 3% SFH in substitution (wt:wt) of the whole diet improved AMEn without showing any negative effect on growth performance of the birds
